[GitHub] [arrow] jorisvandenbossche commented on pull request #9161: ARROW-11049: [Python] Expose alternate memory pools

   Looks good, no comments on the Python code. Maybe not critical for *this* PR, but I have some suggestions (or questions) for expanded docs:
   
   - I would add some more text to the `python/memory.rst`. There is now "PyArrow uses a default built-in memory pool, but depending on how Arrow was built, there may be additional memory pools to choose from."  
     -> Could mention which different options are possible (system, jemalloc, mimalloc), referencing the API page with the overview of the related functions  
     -> Is there a way to see interactively which one is being used?
     -> Can you switch the pool being used? (eg do `pa.set_memory_pool(pa.mimalloc_memory_pool())` ?
